Re: AC3 sound channels are messed up/switched
you do not own a Onkyo TX-SR508?
because in some models there is/was this issue.
and if so you are free to contact onkyo if you want this fixed.
if you have a different amplifier, (okay i did not read well,
you have an other amp because the one i mentioned has hdmi)
is it possible it is due to the file itself?
does the problem also occur in a m2ts file?
and which firmware are you using on your PV73700?
